ZEROtherm BTF80/BTF90/BTF92 O.E.

In this review we will examine immediately three cooler APACK zEROtherm, which are very close each to other. Two models zEROtherm BTF80 and ZEROtherm BTF90 are practically twins and are distinguished only by the material radiator used ( BTF80 aluminum and in BTF90 copper); therefore here we will study only BTF80.

On the face side there is information about supported processor socket . On the reverse and lateral sides it is possible to reveal technical characteristics, and also the comparison with other cooler models :

This cooler (APACK zEROtherm) was made in Korea.

Each cooler come coupled with the following components:

Cooling unit are just beautiful.

The cooling systems BTF80/90 and BTF92 is identical. There are four copper thermal tubes with 6 mm diameter .

The weakest cooling system succeeded to overclock the four core processor to 4.0 GHz with 1.6 v .

All tests were under Windows XP professional edition SP2. For temperature monitoring we used the utility SpeedFan.

All technologies of automatic fan speed adjustment were switched off .

We used OCCT (OverClock checking tool) version 1.1.1b in peak load mode , with 23- minute testing period :

Room temperature during the test was controlled by electronic thermometer, in was maintained in the range 24.5 ~ 25 degree Celsius . I

the effectiveness of cooling systems

Here is the result obtained :

First we note the minimum difference in temperature between aluminum zEROtherm BTF80 and copper model BTF90.

In addition the overclocker model zEROtherm BTF92 O.E has about the same performance as other two cooler.

The cooler zEROtherm nirvana NV120 premium show better result and this is logical. But here Nirvana about equal to super-cooler thermalright ultra-120 eXtreme.

But where is the result of ZEROtherm BTF95 fanless? This passive cooling system was not able to overclock the four core processor to 4 gigahertz. For such propose BTF95 fanless was not developed. But here it is able to cool intel core 2 Extreme QX9650 at default setting and with peak temperature 68 degree Celsius:

In addition zEROtherm BTF95 fanless is able to overclock the four core processor to 3.41 GHz :

This is completely worthy results for such decorative cooler.

Noise level measurement

The noise level results are completely regular in all case .

Conclusion

zEROtherm nirvana NV120 premium with only four thermal tubes ( diameter 6 mm ) demonstrate the same effectiveness as Thermalright ultra-120 eXtreme. There is no Deficiencies;
